This invention relates to a window construction, and more particularly to a weather-stripping assembly for a window construction.

The object of the invention is' to provide a weather-stripping assembly for windows of the type having vertically-slidable sashes, the weather-stripping serving to provide a weathertight joint between the sashes and the window frame, whereby the passage of air currents and the like between the sashes and window frame will be prevented.

Another object of the invention is to provide aV Weather-stripping assembly which will effectively stop the ilow of air, dust, rain and the like around the slidable sashes of a window construction, the weather-strip assembly serving also to help maintain the sashes in alignment and insuring eicient operation thereof.

A further object of the invention is to provide 'a vweather-strip assembly which is extremely simple and inexpensive to manufacture.

Other objects and advantages will be apparent during the course of the following description.

The frame 2i) includes a rst vertically disposed side jamb 22 and a second vertically disposed side jamb 23 which is arranged in spaced `parallel relation with respect to the side jamb 22,

Figure 1.

Slidably arranged between the side jambs 22 and v23 are the usual pair of window sashes, the lower window sash being designated by the numeral 24, while the upper sash is designated by the numeral 25. The lower sash 24 is provided with a pair of longitudinally extending arcuate grooves 26 and 21, the grooves 26 and 21 extending longitudinally along the sides of the sash 24. The upper sash 25 is also provided with a pair of longitudinally extending grooves 26 and 21 for a purpose to be later described.

` Arranged contiguous to the inner face of the side jamb 22 is a body member 28 which is preferably fabricated of a metal that is not alected 'to receive therein the usual sash balance rods 33,

the sash balance rods 33 serving to maintain the vslashes-immobile in their adjusted positions.

` The body member 28 is further provided with a rst lip 34 that is adapted to be embedded in the blind stop 2|, the body member 28 having a second lip 35 embedded between the filler strip `I8 and the inside trim stop I9, whereby the body member 28 will be rigidly connected to the window frame, Figure l.

The side `iamb 22 is further provided with a pair of rectangular, longitudinally extending, spaced .parallel cutouts 36 and 31. The body member *.128 also includes a pair of spaced parallel, rectanvgularly-shaped, longitudinally extending sockets fiside jamb 22.

ifis'fa pair of movable'ribs 40.

' 'l Adjustably connected to the body memberl 28 One of the ribs .Q40 is provided for each of the sockets 38 and 39, and the ribs 40 are mounted for movement into and out of engagement with the grooves 26 in the lower and upper sashes. The ribs 40 have a substantially U-shape and a plurality of spring members 4I serve to urge the ribs 40 into the grooves 26 in the sashes, the spring members 4l being secured to the web portions of the sockets 38 and 39, as by welding.

For maintaining the ribs 40 operatively connected to the body member 28 there is provided a pair of flanges 42 which are integral with each of the ribs 40. The anges 42 are adapted to abut or contact a pair of shoulders 44 on the body member 28, whereby the parts of the Weather-stripping assembly will be maintained in operative or assembled relation at all times. This arrangement permits the ribs 49 to move in and out of the sockets 38 and 39, so that there will be provided a tight fit even after the grooves 26 have become enlarged through usage, shrinkage of the sash, or constant wear thereon.

The other side jamb 23 is provided with a pair of longitudinally extending, spaced parallel recesses 41 and 48 on its inner face. Arranged contiguous to the side jamb 23 of the frame 20 is a support member 49 which is also constructed of a non-corrosive material, and the support member 49 includes a pair of arcuate projecting portions 50 and 5I that seat in the recesses 48 and 41, respectively. Suitable lips 52 and 52' are arranged on opposite ends of the support member 49 and are adapted to be used for the same purpose as the previously-described lips 34 and 35. The arcuate projecting portions 5U and l of the support member 49 are for receiv- 5 ing therein the usual sash balance rods 33.

The support member 49 is further provided with a pair of spaced parallel, longitudinally-extending, projecting portions 53 and y54 which slidably seat in the grooves 21 in the other side of the upper and lower sashes of the window.

Referring now to Figure 9, there is shown a slightly modied body member 56. The body member of Figure 9 diiers from the previouslydescribed body member 28 in that the body member 56 is adapted to be used in those window constructions which use sash cords rather than sash balance rods. Thus, it will be seen that the body member 56 is provided with a pair of spaced parallel sockets 38 and 39 for receiving therein the spring members 4I, but there are no arcuate portions 3| yand 32 in the body member 56, since the sash cords can hang alongside the sockets 38 and 39, whereby the position of the sashes can be adjusted thereby.

From the foregoing it is apparent that a weather-stripping assembly has been provided wherein the air current, dust, rain and the like will be prevented from passing through or between the window sashes and the frame. The weather-stripping assembly includes arcuate portions for receiving therein the sash balance rods which are used in maintaining the sashes immobile in their adjusted positions. Further, the provision of the movable ribs 40 and the spring members 4| insures that the ribs 40. will be urged into the grooves 26 in the upper and lower sashes, so as to provide a tight joint between the sashes and Window frame. The ribs will be maintained in operative relation, and the upper and lower sashes 24 and 25 will be urged against the projecting portions 53 and 54 of the support member 48,' so that a vtight vjoint will be .provided all the way around the window sashes. However. the movable ribs 40 .insure thatnormal-xslidins 4 movement of the sashes 24 and 25 will not be impaired. In the body member 56, shown in Figure 9, there are no arcuate portions for receiving sash balance rods, and the body member 56 is adapted to be used when the usual sash cords are used to manipulate the window sashes.

When using the weather-stripping assembly of the present invention, the sashes will be held in perfect alignment so that tipping of the sashes will be prevented and the sashes will operate quietly and easily. Further, the ribs will eliminate improper function of the sashes which might result from shrinkage of the parts.
